FiiO Q3 THX DAC and Headphone Amplifier (FIIO-Q3)

Natural great sound you can’t hide

THX’s patented feed‑forward error‑correction technology delivers lower coloration and lower distortion, balancing sound quality with driving power. Warm, true-to-life detail and emotionally impactful sound are reproduced clearly right by your ears – without holding anything back.

Equipped with the new AK4462 DAC

Uses AKM’s new low‑power VELVET SOUND–class DAC AK4462. Compared with the previous‑generation AK4452 DAC, it improves the signal‑to‑noise ratio and supports native DSD512 decoding.

Only with powerful performance can decoding be truly uncompromising

Equipped with the same XMOS XUF208 USB decoding chip used in FiiO’s flagship DAC/amp models. Supports 768 kHz / 32‑bit decoding and DSD512 hardware decoding, easily handling higher‑spec music formats.

• XMOS XUF208 | decoding chip
• 768k/32‑bit | high sample‑rate support
• DSD512 | DSD hardware decoding

A headphone‑amp shape that feels even better in the hand

Continuing FiiO’s classic portable amp design language over the years: elegant, solid curves; clean, rational lines; and a smooth, hand‑friendly all‑aluminum CNC body with fine sandblasting – creating a rugged look that’s both practical and attractive.

More interfaces, more fun

Equipped with 4.4 mm / 2.5 mm balanced jacks and a 3.5 mm single‑ended headphone jack, covering the common portable‑player headphone interfaces. In addition to balanced decoding + amplification, it also supports single‑ended input with balanced amplification, letting you enjoy more of the balanced‑listening experience.

*Output priority order: 4.4 mm balanced = 2.5 mm balanced > 3.5 mm single‑ended. If 4.4 mm and 2.5 mm are plugged in at the same time, neither will output.

The moment playback starts, light up your passion

An RGB sampling‑rate indicator light has been added to the volume knob. Different colors represent different sampling rates, so you can tell at a glance during every listening session.

Blue: ≤ 48 kHz
Yellow: > 48 kHz
Green: DSD

Before your fingertips even notice, it’s already responded

For professional audio products, the most classic adjustment method is the analog potentiometer volume knob. With ADC curve reconstruction, it effectively solves the low‑volume left/right channel imbalance that can occur with traditional potentiometers, greatly improving adjustment precision. Before you even think about it, it quickly adjusts for you.

Long battery life

Even with upgraded high‑performance hardware, it still offers long battery life. Built-in 1800 mAh battery; when used for USB decoding, battery life can reach 10+ hours, meeting everyday music listening needs.

Reversible Type‑C – plug in and use instantly

Uses the more popular USB‑C interface, compatible with more devices for digital decoding. It also supports USB Power Delivery (PD) and can be charged from a computer’s USB port.
